Application filed March, 1925. Serial No. 16,693.

To all whom it may'ooncern: I

Be it known that I, JOSEPH S. OEoHsLn, a citizen of the United States of America,

residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvement's in Tractor-AttachmentFrames,

of which the following is a specification.

This invention relates to portable power units embodying a standard type tractor and work utility, and it has more particular reference to supporting frames therefor..

The fundamental object of my present improvements, accordingly, is to provide a supporting framework of the type referred to embodying characteristic features hereinafter fully set forth, typically illustrated by the accompanying sheet of drawings, and tersely recited in the sub-joined claims.

.In the drawings Fig. 1, is a side elevation of my novel tractor attachment frame as particularly adapted to a portable asphalt pavement heater-'for road repairing and making; the utility being outlined in dot-and-dash lines,

in order not to conflict with a clear understanding of the present invention. Fig. 2, is a top plan view of the same. Fig. 3, is a vertical section taken substantially on the plane indicated by the arrows 3-3 inFig. 1.

Fig. 4, is a fragmentary perspective view later on specifically described.

Fig. 5, 1s a fragmentary section illustrating a rear bumper assembly and anchoring means hereafter explained.

Fig. 6', is a fragmentary section showing a fire tube support. i

Fig. 7, is a broken perspective view of the upper frame assembly; and,

Fig. 8, is further fragmentary perspective view of a portion of the upper framework; Referring more in detail to the several views a conventional type of tractor is comprehensively indicated by the numeral 9,

said tractor having road and steering wheels 10, 11 respectively. A fuel oil tank is indicated at 12, and a fan blower at 13, the

latter having an overhead conduit 14, and elbowed down draft extension 15, for the purpose of concentrating the frame from an appropriate burner-not shownon to the surface being treated. All of the foregoing parts are briefly referred to by way of better explaining my invention, but do not form any part thereof.

My novel tractor attachment frame now to be described broadly comprises a lower framework 16, and a super-structure or upper framework 17, appropriately secured rigidly together by clamp bolts 18, whereby the said superstructure may'be readily detached and the unit'adapted for other purposes thanthe specific one referred to.

The lower framework 16, comprises spaced longitudinal I-beams 19, 20, bolted or otherwise secured together at 21, in stepped relation, and connected together by transverse channels 22,23, as well as by "a stirrup 24, of channel section affording a r gid support for the tractor front suspens1on pm 24. These several transverse members 22, 23 and 24, are preferably lock 7 welded to the longitudinals 19, 20, although they may be otherwise rigidly secured in place. Attention is hereby particularly directed to the rear transverse channel 23, as best shown by Fig. 5, which is fitted with a back bumper 25 of channel section which is butted there-against in web to web relation or with the flanges of said bumper outwards. This'bumper 25 is also of a length as best shown by Fig. 2 to adequately protect the fuel tank 12, above referred to. Connecting support for the framework 16,

relative to the tractor 9, is also effected by means of clamp members 26, snugly embracing the tractor rear axle housings 27- Fig. 2.

Referring now to the superstructure 17, it will be seen, the same comprises spaced longitudinal I-beams 28, rigidly retained in parallel relation at their forward ends by a cross channel 29, appropriately notched out at 30-Fig. 7-and integrally welded thereto. Further, rigid special relation of the I-beams 28, is ensured through the medium of stirrup straps 31, having their ends welded at 32-Fig. 6to the web and lower flanges of said I-beams. These stirrup straps 31, afford support for the hereinbefore referred to overhead conduit 14, as will be readily understood without further explanation. Verticals 33 of I-section, and similar size to the longitudinals 28, are welded at34, to

the lower flanges of said longitudinals and reinforced against torsional straining by 'gussets 35 welded at 36Fig. 8in place. Braces 37 of I-section, and like size, are similarly welded at 38 and 39, to the longitudinals 28 and verticals 33, respectively, to afford adequate support and rigidity to the outboard forward end of the superstructure 17.

F cot-plates 40, are also weldingly attached at 41Fig. 4to the lower ends of the verticals 33, and provided with holes 42, for the passage of holding down bolts 43, whereby the superstructure 17 is removably attached on the lower framework 16. The forward foot plates 40, are provided with integral hooks 44, to accommodate anchor-- ing means for the funnel'not shown-0f the down-draft extension 15.

In addition'to the foregoing means, ef

,fective to rigidly brace the superstructure 17 against torsional deflection, I weld at their ends 45, intersecting bars or flats 46- Fig. 3to the. web and flanges of the forward verticals '33, the same being also 51Fig. 1. A bar or rod 52Figs. 1 and 2is,an-

. chored at 53, to the superstructure 17, as

well as to the rear transverse channel 23,

, of the lower framework 16; thereby tying said superstructure and framework together and evenl distributing the load.

From t e foregoing it is thought the inherent rigidity and obviousadvantages of mynovel tractor attachment frame will be fully appreciated without further elaboration. Furthermore, the right is reserved to make such detail changes as fairly lie within the scope of the subjoined claims; for example the superstructure 17 may be integrally joined to the framework 16, by welding the verticals 33, to the upper flanges thereof.
